King Shocks Returns as Supporting Sponsor of 2023 California 300

For the second consecutive year, King Shocks will return to the 2023 California 300 as a supporting sponsor, event officials announced today. King will be on hand on the Start/Finish Line Midway throughout race week, which returns to Barstow, California on October 4-8, while King-equipped racers will compete for race victories throughout numerous classes.

“King Shocks is one of many partners from last year’s inaugural California 300 that we’re thrilled to have back,” said Mint 400 CEO Matt Martelli. “Year after year, top off-road racers at all levels rely on King products to conquer the desert, and they’ll be on many of the top entries in this year’s race as always. Be sure to check them out on the midway before watching their racers in action and seeing if they can defend last year’s overall win!”

“All of us at King Shocks are excited to have racing back in Barstow with the second annual California 300,” said King Shocks owner and president Brett King. “It’s our testing grounds for our suspension systems, so we’re always excited to compete here. We can’t thank the Martelli Brothers and the whole Mad Media team enough for bringing back racing to Barstow in a professional manner, and we’re looking forward to another great race this year!”

Last year’s inaugural California 300 saw Grabowski Brothers Racing take the overall event victory while riding on King Shocks, despite competing in the Unlimited Truck Spec class rather than the more powerful Unlimited Trucks. They’ll be back to defend their victory, while other King-backed racers will also look to complete a sweep of Unlimited Truck wins in the inaugural Unlimited Off-Road Racing Triple Crown; Adam Householder and Eric Hardin won the first two races of the year, and both will be on hand to battle for the victory and class title in Barstow.
